Yep, you read it correctly; 2.20GHz on the stock voltage! :Q I haven't even pushed it yet...it's late and I've got to get to bed...will mess with it tomorrow.

Pic of the stepping.

Yes, it's old; but I just took it out of the box (Retail Box) tonight. It's been in storage since May 2003. :(

Right now I'm doing the P95 TT...so far so good. Ran one loop of 3DM2003, all good.

Being that I'm hitting 2.20GHz on stock voltage (11 x 200) ...I don't see me having a problem hitting 2.3 or maybe 2.40GHz at say, 1.800v. :D

If I could get to 2.40GHz, I'd be very happy for awhile. That would be about a 20% increase in CPU speed from what I had. (2.00GHz)

Thoughts?

ps
It's in a NF7-S v2.0...haven't updated my System Rigs Profile yet.

pps
Anyone know anything about the stepping? Obviously, it's decent...but is it a "Killer?" I'm going to bed to dream of 2.40GHz. ;)

My chip is 2 weeks older than yours. :) They are decent chips and they can hit 2.4GHz on air frequently. :)

BTW: I told you that chip would do 3200+ on stock voltage with the NF7-S. :beer:

Should have gotten a mobile. I'm doing 2.4ghz on "stock" voltage.
It was just laying around?

Yes, packed away from what I remember. What a nice find though, eh? I wish I had hardware packed away that I had forgotten about. ;)

Hmmm, maybe I should go look through my things. Anyone think there'd be an FX-53, you know, hidden under an nForce3-250 mobo?:D

LOL guys!!! It wasn't "forgotten" or "laying around" by any means. I bought it last year and suddenly got sent on back to back extended business trips and I moved...twice.

I just got my stuff out of storage last week. :)

MEGATOMIC: You're right; you DID tell me. I"m so happy you were correct! :beer::cool:

Tonight I'll see what more I can wring out of it. I still have no idea how high my Corair XMS3200 will go, as my old 8RDA+ would do 200MHz, but not a drop more.

I may be proven wrong, but being that the chip is doing 400MHz over stock at default voltage, I don't see why it wouldn't do 600MHz over w/a little kick in the ass, voltage wise. *crossing fingers*

Oh goodness no!! :Q I doubt anyone could get a good OC like this w/the stock CPU HSF.

The first rule of overclocking is to upgrade to a better HSF.

I'm using what is considered to be the second-best (not by much though) Socket A HS right now.

Thermalright SLK900A

with this


Panaflo 92mm medium-speed fan.

I'm also using Arctic Silver 5 thermal interface material (TIM). AKA the goop that goes b/t the CPU and the base of the HS.

good job. my 2500+ did 32--+ on stock voltage but only passed prime95 for an hour. 0.05 bump in voltage and it's good to stay. i can't push it it to 11x210 .. but im sure if i tweaked a few settings, i could hit it.

It's dead rock stable at 200 x 11 @ 1.600v. Just stopped a 17-hour P95TT. 0 errors, 0 warnings. Stress temp is only 46C, which is darn good!! Gotta luv the SLK900. :):heart:

I am very tempted to push my luck and see how high I can go....I hate instability though.

What to do?

Well, you chip is somehow magically doing just as well as my Mobile Barton 2500+. For the record, mine runs 100% stable at 2500mhz at 1.80v. You will notice a very nice performance boost at this speed, it's very noticeable. If it were me I would overclock the crap outta that CPU. It's worth less than $100 ATM. If it dies it's easy to replace, and the chances of it dying are extremely remote unless you pump over 2.00v or something into it.

Hey, I appreciate the brutally honest opinion. :cool: It does seem that I got a good chip, for ONCE! :) I mean, I've got a good PS and a good HS...but it's still at the stock voltage. It's so good I'm almost afraid to fck with it. Almost.

Before upping the FSB, I figured I should try to see where my RAMs' limit is. (Corair XMS3200C2, which is rated at CAS2.5 in dual channel) I upped my RAM timings to 7-4-4, CAS2 and have been running a P95TT for about two hours now. All is well.

My SANDRA2004 memory bandwith with this config is 2988MB/s....damn good.

I would gladly go back to CAS2.5 for an extra 10MHz in bandwith. I plan on going for 205MHz, then 210...we'll see what happens. I'll report back here.

With any overclocking, it's all about STABILITY, IMO. If it cannot do at least 12 hours of P95TT w/o erroring out, then it's not a stable OC IMO.

Nice work man.

But I disagree wth your rules.:) My son runs a barton 2400 OCed to 2.34 on a $8 HSF (but we do use AS3). HS and temps are largly overrated in my experiances. This is from someone who main rig is water cooled.

I wouldn't mess with the FSB if I were you, it's too complicated, especially since you already have your RAM running at nice timings.

Just give it a shot at 11.5x200 or something. That should most definately work at 1.75v or so. Then try 12x200, this time at maybe 1.885. If you're lucky, it will do 12.5x200 at 1.80v like my precious chip does. Good luck. :) :beer:

Yes, he already told us that. <EDIT: Or did he?>

Since he had it in storage for a year I would guess it is unlocked.

Hello everyone.

According to what I've read, around Week 32 is when they started locking the multi. This CPU is a Week 15, which puts it's date of manufacture around mid-April, 2003. It SHOULD be unlocked, but I have not tried changing the multi.

I'm an old-school overclocker; FSB is where it's at. Bandwith is your friend. :D BUT, you guys do have more experience with OCing Bartons than I do...I'll try the multi first and see what happens.

I'd love to have a 2400MHz CPU, whatever the configuration....as long as I've got a 200MHz FSB at least, I'll be happy.

Thanks for posting in this thread. This place would be "no place" w/o you guys. :)

Don't count on getting past 2.2 GHz. For a while there Bartons were hitting a wall at 2.2 GHz. A lot would do 2.2 on default voltage, then require 1.75 to get to 2.25, and over 1.8 to get to 2.3. It wasn't until late last year that they started to dramatically improve, but then the multipliers were locked. Then mobile Bartons became more popular since they're higher quality and have unlocked multipliers.

:Q DAYUM. I really haven't paid as much attention as I should to the whole "Mobile" vs. "Desktop" vs. "All the other AMD chips I don't understand ATM" debate. My bad.

From what I've seen, you guys that get good chips are getting insane overclocks. The problem seems to be getting that good chip. I.E. you have to watch the IBBs for a post from someone stating "Buy the XYZ from Newegg right now!!! Make sure its' the XYZ124 stepping!!" AND then you get lucky. I don't have time for that though.

I tell you this much; just an extra 200MHz on the CPU has netted me a tidy little increase in game performance and benchmarks. I can only imagine what 2.50GHz, an extra 500MHz would do for me. :cool:

Nice OC, myocardia. :)

I picked up that 2500 barton/ ECS nf2 combo at frys for $70 and it was running fine at 200 FSB. I didn't do much testing (3dmark01 = 14.5k), but I'm pretty happy for the price and getting it that fast with not many bios options. No volt adjusters in there. The ram was holding me back from going anywhere higher or using lower latency timings, but this rig will hold me over til the new stuff comes out and drops in price.

Hopefully I'll be able to keep it stable without getting a better cooler or ram.
